KT-20 MAGNETIC SUSCEPTIBILITY AND CONDUCTIVITY METER

KT-20 MAGNETIC SUSCEPTIBILITY AND CONDUCTIVITY METER The KT-20 is a handheld instrument capable of measuring the magnetic susceptibility, conductivity or density of a sample. Its modular design provides users the ability to employ different sensors that are of an optimal frequency for either magnetic susceptibility or conductivity. The sensors are available in circular and rectangular designs and can easily be interchanged, allowing the KT-20 to measure smaller or larger sized samples or cores. Density measurements can also be obtained from the KT-20 providing more information about the sample. A picture, audio note, text note and GPS coordinates can also be added to the measurement to increase the amount of information one can attach to each record to improving archiving. Interchangeable Sensor Transflective Colour Display KT-20 S/C Scan Mode Benefits: Three models to choose from: a dedicated magnetic susceptibility meter, dedicated conductivity meter, or a combined magnetic susceptibility/conductivity meter. Microphone 5-Button Multi-Directional Keypad Light Sensor Digital Camera (on reverse side) Interchangeable dual- and single-frequency sensors in circular and rectangular designs. Speaker High Sensitivity for magnetic susceptibility (1 x 10-7 SI) and conductivity (0.1 S/m). Density measurements using the KT-20 with the accessories provided with the system. Bracket for Tensiometer Battery, DC Input and USB Communication IP/Resistivity sensor will become available later. Data profiles displayed in real-time while scanning. Built-in high resolution camera to capture pictures of samples. 1

Split and full core corrections for standard drill rod diameters (AQ, BQ, HQ, NQ and PQ) and non-standard sizes (2.4 to 12 cm). Input core box information to correlate measurement results to their appropriate depths. Data running average and standard deviation values displayed during individual measurements. Built-in microphone and speaker. Upgrades and support available via the internet. KT-20 S/C Data Profile Applications include: Density Measurement Virtual Keyboard Mineral exploration Core analysis Oil and gas exploration Environmental investigations Agricultural research Archaeology 2

Sensors Five sensors are available in dual and single frequencies to provide certain benefits for either magnetic susceptibility or conductivity measurements. State-of-the-art design enables sensors to be easily interchanged. Circular and rectangular sensor designs available to adapt the KT-20 to large and small sized samples (note: 10 khz singlefrequency sensor is only available in a circular design).
